John McEnroe questions medical time out rules after Rafael Nadal's injury

John McEnroe is never banal when he speaks about tennis. And his commentary match on Tuesday when Rafael Nadal was dealing with a right leg during the fourth set of the quarter-finals meeting against Marin Cilic, was really interesting.

McEnroe thinks the rule about medical timeout could be reviewed, as it is used too often, despite in cases like this, the player was really suffering. 'Do you have to have an injury that occurs during the match? Are you able to say I'm a little tired can I have a rub on my legs? Is that considered a medical timeout? I'm sure any spot in a tennis player's body, if you press hard enough it'd hurt', McEnroe said.

'I need to study up on this. I do feel like it's being abused - and I'm not saying it's being abused right now - but the timing of these timeouts very rarely are coincidental. Bathroom breaks etc. And if it's within the rules you can't blame them.
